Improvement in means for creating artificial currents



UNITED STATES PATENT; OFFICE. N

EDWARD BANTZ, OF BALTIMORE, MARYLANDU IMPROVEMENT IN MEANS FOR CREATINGARTIFICIAL QURRENTS.`

Specification forming part of Letters Patent No. 139,854, dated J une17, 1873 application filed` October 31, 1872.

To all whom it may concern:

Be it known that I, Itnwmtn BANTZ, of Baltimore, in the county ofBaltimore and in the State of Maryland, have invented certain new anduseful Improvements in Apparatus for Greatitiig Currents in Water; anddo hereby declaref that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawingsand to the letters of reference marked thereoninmking a part ot' thisspecification.

The natureot' my invention consists in the construction and arrangementof an apparatus for creating currents in water, as will be hereinaftermore fully set forth.

ln order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichrepresents a horizontal section of my apparatus.

A represents a tunnel of any suit-able dimensions, divided at anydesired point into two branch tunnels, B, which may be substantially inthe form shown, and then again connected to form the main tunnel. Thebranch tunnels or sewers B B should each be halt' segments ofthe maintunnel or sewer, and a space, C, left between them. D represents a shaftrunning lengthwise between the two branch tunnels, and its ends enteringthe main tunnel at both ends of the branch tunnels, where said ends ofthe shaft are support ed by one or more bars or supports a. Upon eachend of the shaft D is placed a screw- Wheel or propeller-wheel, E, whichshould be of alittle less diameter than that of the main tunnel. Theshaft D with its wheels E E is revolved by any suitable power connectedwith the center of the shaft by any suitable and convenient means. y

This apparatus is designed for use wherever an artificial current ofwater is needed#- forinstanoe, in harbors or basins where the water,especially during the summer months, becomes impure. Then by digging atunnel or sewer connecting the inner end ot' such harbor or basin withthe stream or river, and at a suitable point in said tunnel or sewerform thc branch tunnels and locate the shaft and wheels a current may becreated and main-- tained throughout the entire basin or harbor whichwill eifectually prevent` any oiiensive odors arising from thewater, andkeep itconiparatively pure.

The size ot' the tunnel depends upon.tl1e volume of water desired to bepassed through in a given time.

The same apparatus may be used with advantage in ventilating publicbuildings, a current of air in that case being created instead ot' acurrent in water.

Having thus fully described my invention, whatI claim as new, andldesireto secure by Letters Patent, is

The tunnel or sewerA with the branches B B, in combination with theshaft D with wheels E E, substantially as and for the purposes hereinset forth.

In testimony that I claim the foregoing I have hereunto set my `handthis`22d dayof October, 187 2.
